A: Ok. Let me show you. If we use FB, we can capture information very fast because FB is a social network that everyone shareS information, images, news, emotions, etc… with THE speed of seconds. Especially there are many pages on Facebook that teach English for free and you can contact teachers and foreigners to improve your English.
B: I see. But I can be addicted and I can’t focus on learning ANYmore. Seriously, there are many hackers who can steal our information. Moreover, spending more time on mobile phone or computer can easily get YOU ill and it’s also harmful to our eyes.
A: I understand but if we use it reasonably and allocate time to use it, our health will not be affected much. On the security problem, there are many apps on the Internet that prevent hackers and protect personal information. You should also limit texting with strangers, post fewer photos and always keep your personal information in private on social networks.
